ABSTRACT:
A hydrocarbon conversion process wherein a fractionation column overhead vapor stream is circulated through a portion of the process, such as through a purification zone or hydrocarbon recovery zone. Part of the motive force for this vapor circulation is derived from depressurizing the vaporous phase of a mixed-phase reaction zone effluent through an ejector which draws a suction on the overhead receiver of the fractionation column.
